Answer:

1.75 moles are contained in 500 mL of a 3.5 M NaOH solution.

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case:

  • molarity= 3.5 M
  • number of moles of solute= ?
  • volume= 500 mL= 0.5 L

Replacing:

[tex]3.5 M=\frac{number of moles of solute}{0.5 L}[/tex]

Solving:

number of moles of solute= 3.5 M*0.5 L

number of moles of solute= 1.75 moles

1.75 moles are contained in 500 mL of a 3.5 M NaOH solution.
